Application filed September 18. 1912. Serial No. 720,879.

Referring now to Fig. 1, I have shown therein a main frame 1. upon which is journaled a shaft having a power wheel 3. The top hoard of the frame is formed by a bed plate 1 having rack teeth 5 on its lower side near one end of the machine. These rack teeth are for the purpose of cooperating with a pinion 6 tsee 3 and 9) which'is operated by a handle 7. Slidahly carried by the bed plate 1- is a carriage. 8. This carriage has a portion which extends downwardl and surrounds the shaft -2. An cc centric 9 is mounted on the shaft 2, and is lieved. thereto as to slide longitudinally of the shaft, but to be operated through the rotation of the latter. A gear10 is also lie -fed to the shaft in a manner to slide longitudinally therewith and is arranged to mesh with a gear 11 on a shaft 12 journaled' on the carriage S. p I

Referringnow to Figs. 9 and 10, it will be seen that the eccentric 9 is connected by a rod 13' with a hell-crank leverll. The latter is connected to a reciprocating slide member 15 hearing upper saws 1(3 and lower saws 17. The device is so arrznged that when the eccentric is in motion the slide 15 reciprocates so as to cause the reciprocating movement ot' the saws,

The means for holding the boards which form the janihs hest shown in Figsx3 to 5 inclusive. there are four jaws, 18, 18-. 19 and 19. respectively; These jaws are pivoted on a common pivot "20 carried bv the extension 8- of the carriage 8. A. spring 21 is disposed between the jaws 18- and 19". V A. spring; 22 is disposed between the jaws 18 truth 18,

while a spring 23 is disposed between the jaws 19 and 19. As will he seen from Fig. 2 there are three sets of these clamping devices disposed at A, l? and. C respectively. A common rod '21 extends through hracltets 25 carried on the upper nien'iher of the jaws. Each clamping oevice is provided with an arm 26 (see Fig. 3) which is secured to the shait 3'1. and which has a pivotal connection with the lint: 27 connected with the lower jaw 19. A rigid abutmentlmeinber 28 extends Zorwardl from the'carriage, 1'. (3., in the opposite direction from the extension 18. This abutment'niember supports the inner jaws in their operative position. i

The boards for forming a door 'or window jainh, such as those, shown at '29 and in Fig. 4, are placed on the members 19 and 18 As will be seen from Fig. 3

and are pushed inwardly until they strike the stop members 31. The two inner jaws .are held apart by means of the spring 21,

and the outer jawsare kept apart by means of the springs 22 and Now if any one of the handles 33, which are on the square rod (see Fig. 1) be thrown into the position shown in dotted lines in Fig. 3, the jaws will be forced together so as to clamp the boards in the horizontal position shown in the figure. It will be noted that in this movement the boards are brought nearer together. While they are being moved together they are operated on by the cutting mechanism, as will be hereinafter explained.

Referring now to Figs. 6, 7 and 8, it will be seen that the shaft 12, which, as stated before, is operated through the medium of the gears 11 and 10, bears a gear 34 carried between the links 35 and arranged to mesh with the gear 36, which is also disposed between the links 35 and between a pair of outer links 35. The gear 36 meshes with a gear 37, which has integral boring members 38 and 38 extending from it. ()ne'end ofthe links 35 is pivotally mounted on the boring devices 38 and 38, while a frame 41 is also pivotally mounted on the boring devices 38 and 38". This frame carries a second gear 39, meshing with the gear 37 and is provided with boring devices 40 and 40. A handle 41 is provided for manipulating the frame. Arranged to pass through bosses on the frame are the guide members 42. Referring now to the clamping mechanism, it will be noted that when the lever 33 is shifted the boards are brought together in the manner-described. As will be seen in Fig. 7, the boring tools will bore holes in the boards as they are brought to gether by the clamping device. Now if the handle 41* is shifted laterally into the dotted line position shown in Fig. 6, these boring devices, which are also cutters, will cut longitudinal openings, such as those shown at 43 in Figs. 6 and 13. In order to get a clean cut the boring tools may be moved backwardly and forwardly by the handle 41 until the desired result is obtained.

It will be noted that the reciprocation of the saws. 16 and 17 is occasioned through the eccent ric' 9 and the members 14, 15 and 16, as. already explained. \Vhen therefore the boards 29 and 30 are brought down upon the saws, the latter will cut channels in the boards transverse to the longitudinal axis thereof. In Fig. 6, I have shown the upper saws 16. I may arrange transverse teeth 16 between these saws, so as to cut out the material between the two, saw kerfs formed by the saws 16. If desired these teeth 16inay be omitted and the material may be removed by hand. There are two of these dado cutting devices. In Fig. 11 I have shown an oblique or diagonal dado cutter. In this figure the eccentric 9 on the shaft 2 is connected by means of a rod 13-" with a bell-crank lever 14 connected with a reciprocating carrier 15 havin upper and lower saws 16* and 17 respectively. The frame 45 which carries the reciprocating member 15 is pivotally mounted upon a bracket 46 carried by the table 4.. This support 45 is slotted at 45- (see Fig. 2) and is provided with locking bolts 47, which may be tightened to turn the support atany desired angle. In view of the fact that the rod l3 is coincident with the axis of rota tion of the support 45, the dado cutter may be moved to any suitable angle and the eccentric 9 will still operate to drive it.

Referring again to Fig. 1, it will be seen that on the shaft 2 is a third eccentric 48, which is connected by means of a rod 49 (see Fig. 14) to the swivel joint 50, attached to a shaft or rod 51 which slides in a vertical bearing 52 carried by a frame 53 secured to the bed plate 4. The rod 51 has two pivoted connecting rods secured to it. One ,of these connecting rods 54 is on one side of the rod 51 and the other 55 is on the other side (see Figs. 14, 15, 16 and 17). The connecting rod or pitman 54 drives a crank shaft 56 (see Fig. 16) while the connecting rod or pitman 55 drives a crank shaft 57 at right angles to the shaft 56. The crank shaft 56 is provided with the cranks 56 and 56 (see Fig. 16) to which the rods 56 and 56 are attached respectively. The rod 56 is arranged to reciprocate a frame 58, which is carried by acentral support 59 (see Fig. 6). The frame 58 is provided with upper and lower saws 60 and 61 respectively. The crank shaft 56 is extended through the support .59, and the crank 56 reciprocates a'frame 62, bearing upper and lower saws 60 and 61. It will be seen from Fig. 16 that the frames 58 and 62 are 180 apart in their reciprocatory movement. In other words, when one frame is going in one direction the other frame is going in the opposite direction.

The crank shaft 57 is connected by means of links 63 and 64 to the slidable frames 65 and 66 respectively (see Fig. 16). A description of one of these frames and the saws which they bear is sufiicient, since they are both alike. Referring then to Fig. 14, it will be seen that the frame 65 is slidable in a guide 67. Pivotally secured to the frame v65 are arms 68 and 69 which bear saws 68- and 69 respectively for cutting the ends of the pockets. are the saws 68 and 69. The means for opening the arms 68 and 69 to receive the Secured to the frame 65 itself boards 29 and 30 consists of a lever handle 70 mounted on a shaft 71 and connected by alink 72 with a lever 73, the end of which lever 73 is connected in turn by means of the links :74 with a bell-crank lever 75 whose end bears o t theupper portion-of the ran 69. It will be apparent that when the handle is swung intothe dotted line position shown in Fig. ll, it will .cause the separation of the arms 68 and 69, by means of the levers 73 and Y75. Set screws 76 and 77 limit the movement of the arms 68 and 69, while. springs 78 and 79 respectively tend to pull .these arms together.

\ It will be seenfrom Fig.- 16 that the frames (i5 andn66 are reciprocated alteri toinsert a board, such as 29 and 30 in place,

nately, since the ends of the crank shaft 57 are. bent, in opposite y directions. In order the handle 70 is first swung into its dotted --by permitting-the springs 78 and 79 (see Fig. 14) to bring the arms together, thereline position, so as to permit it to be inserted, butnwhen the boards are inserted. it is pulled over into the full line position, there by bringingthesaws 68, 68, .69 and 69 into engagement with the upper and lower sides of both boards respectively.

The pocket cutting arrangement thus far described operates so that thecuts are made clear to the corners.

That is, aside saw '-'will--run' to itslimitand then retract and one board, are not in alinement.

pu y. .OPQiIing 81 an end-saw will run to the end just vacated by the side saw. Thereuponi the otherside -saw; will run into the corner, just vacated by the end saw, whereupon the other end saw "wills run into the corner just vacated by the opposite side saw. This motion continues 'until the pocket is cut through. It will be observed, however, that the upper'and lower end pocket cu'tting saws operating on any This makes a shoulder 80 at the end of the longitudinal (see Fig. 13).

'- same figure the boards 29 and 30 have longitudinal pulley openings 82, transverse dadoes 88 at one end, and oblique dadoes at the other.
